Value Collection 821711MSC Flange Bolt 3/8-16 Unc 5/8 in Grade 8

Product Description

The VALUE COLLECTION 821711MSC is a smooth flange bolt designed for high-strength fastening applications where a built-in bearing surface is required. Sized at 3/8-16 UNC with a 5/8 inch length under head, this bolt is fully threaded and features a 13/16 inch smooth flange diameter. Manufactured from Grade 8 alloy steel with a phosphate and oil finish, it delivers strong corrosion resistance and load-bearing capacity suitable for demanding mechanical and structural assembly work. Licensed trades and industrial maintenance crews rely on this fastener when a traditional washer face is not practical.

This flange bolt is suited for use in mechanical assemblies, equipment mounting, and structural fastening tasks across industrial, commercial, and trade applications. The smooth flange distributes clamp load evenly without the need for a separate flat washer, making it a practical choice in tight-clearance installations or high-volume assembly lines. It meets IFI 111 and SAE J429 standards, confirming its dimensional accuracy and mechanical property requirements for inch-series fasteners.

Key Features

• 3/8-16 UNC thread size with 5/8 inch fully threaded length under head
• 13/16 inch smooth flange diameter provides integral bearing surface
• Grade 8 alloy steel construction for high tensile and proof load strength
• Phosphate and oil finish for corrosion and galling resistance
• Hex drive for standard wrench and socket installation
• Meets IFI 111 and SAE J429 fastener standards

Compatibility

Designed as a standard inch-series smooth flange bolt for use in mechanical, industrial, and structural assemblies requiring 3/8-16 UNC Grade 8 fasteners.

Installation Notes

Install using a standard hex wrench or socket drive sized for 3/8 inch hardware. De-energize or lock out any equipment before fastener replacement in live assemblies. Do not mix Grade 8 fasteners with lower-grade nuts or threaded inserts, as mismatched grades can result in thread stripping or joint failure. Follow applicable torque guidelines from the equipment manufacturer or referenced fastener standards.
